The speed and skill with which on every occasion throughout the war they shifted heavy pieces of artillery from one point to another, or withdrew them altogether, was a new feature in warfare. Except when the garrison of Ladysmith, on two occasions of night sorties, surprised and destroyed three of their guns, they scarcely lost a piece either in the numerous actions during our advance to Ladysmith, or in their final retreat from that town. And similarly on the other side, of the very large number of guns employed at the fight on the Modder, at Magersfontein, and in the siege of Kimberley the whole were, with the exception of a few pieces captured when Cronje was surrounded, withdrawn in spite of the hurried evacuation of their position, a feat almost unparalleled even in an army accompanied only by field-artillery, and extraordinary indeed in the case of works mounting heavy siege-guns. No farther advance was made till the afternoon, when General Buller arrived on the summit of Green Hill, and seeing that Hlangwane was not entrenched on its northern side, which was completely turned by our advance, sent Barton's brigade against it. But the loss of Monte Cristo had for the time quite taken the fight out of the Boers, and after maintaining a brisk fire for a short period, they evacuated the position as soon as the infantry neared the summit, and, hurrying down the western slope, crossed the Tugela. Three camps full of provisions, blankets, and the necessaries of Boer life fell into the hands of the captors, together with a large amount of rifle and Maxim ammunition. The place had been turned into a fortress. Trenches and some breastworks covered all the approaches by which the Boers might look for an attack, and as the whole mountain was covered with huge boulders, they were able to withstand even the storm of lyddite shell that was poured upon them. On the following day Hart's brigade received orders to advance towards Colenso. This was still held in force by the Boers, but was now commanded by guns that had been got up the slopes of Hlangwane, and on Tuesday morning General Hart captured the position without serious loss, the Boers suffering severely from our shrapnel fire as they retreated, some by the iron bridge and others by a ford. Thorneycroft's Mounted Infantry, which was called up in the evening, took advantage of the discovery that a drift existed there, and a squadron forded the river in spite of a scattered fire from the Boers on the opposite bank. Another portion of the colonial force occupied Fort Wylie, a redoubt that had been thrown up by our troops when they occupied Colenso, but had been abandoned when the advance of the Boers to cut the line between Colenso and Frere forced them to retire.
